QTX | 2-Way Crossover | 6dB, 8 Ohm, 100W, 2/2.5/4kHz

I built some boxes and loaded in the crossovers and the drive units. And added black carpet covering. Looked terrible once i put them up..lol so i broke them apart and had a rethink as these are for Dolby Atmos speakers. The Crossovers work fine as expected.

Once you get iver the fact the finishing isng great, these are potentially very good crossovers.A few issues were resolved with 10 minutes of soldering. Firstly, the ceramic resistors are HEAVY, and fragile, this means they can easily under their own weight fall to pieces if subhected to a relatively low force inpact, for this reason I wouod suggest doing what i did, which is to remove them, clean the pcb and then glue them back down using hot glue, then resoulder them. This removed the risk of vibrations and shocks damaging them over time.Secondly, one of the coils is attached with a cable tie, again i removed it, cleaned the pcb and then used hot glue to fix it in position, again removing the risk of vibrations causing damage over time.This is odd, as one of the coils is actually already glued down, so why the manuefacturing process wouldn't also glue the other coil and the resistors is a mystery.Overall the are very good, cutoff is pretty spot on at 3kh and they are actually very well made minus a few tweaks.I would certainly buy them again in the future, bearing in mind the basic mods I would have to do.

recently rebuilt a matched pair of Vintage Kef Celeste VI's that some muppet had overloaded the crossovers , these fit perfectly and are a doddle to fit with some soldering , both the tweeter and the sub are connected to the 2500k output and the speakers sound awesome much better that any modern units.

Works perfectly and is good value for money, but do note, it is a lot bigger that it looks in the picture. (about 90mm X 90mm X25mm).

The sound is good from my speakers, however I noticed that one of them needs +3db to balance with the other. Tested with other crossovers and had no issue. But since they are cheap they will be useful for different projects. So no hard feelings.

Replaced a failed crossover with a pair of these which seemed to match my requirements.The quality of both left and right speakers degraded to unusable at the first gig. It is unlikely they had more than 150-175W going through them.Tested the PA briefly before going "live" and all seemed fine.One side failed during the first set the other in the last number!Be sure that these units have enough "headroom" for your needs. They are cheap and maybe that should have made me a little cautious.

The middle coil is not glued on..!!!

Works fine easy to install

BEN FATTI , CON OTTIMO PREZZO

Para lo que quería bien

Cosa dire ottimi tagli di frequenza buona costruzione ed ottimi componenti.

Ho sostituito i crossover delle mie casse Dynaudio, ormai andati. Risultato eccellente.

il filtro lavora discretamente bene accoppiato a due altoparlanti da 8Ohm (woofer da 10W e full range da 15W)non fa un taglio drastico delle frequenze, il mid range collegato a 2KHz treble lavora in potenza fino a circa 400Hz, poi la potenza cala sensibilmente, il woofer collegato a 2kHz bass lavora in potenza dal suo minimo (circa 45Hz) fino a oltre 3kHz, quindi sarebbe da modificare il filtro per aumentare il taglio "meccanico".il suono restituito è decisamente caldo se confrontato ai filtri crossover 12dB con resistenza sul treble e i bassi sono enfatizzati quel tanto che basta per sentire al meglio batteria e violoncello, soffre un pò l' organo in quanto il taglio non accentuato delle frequenze fa lavorare in parallelo i diffusori dimezzando l' impedenza e portando al limite l' amplificatore (10W a 8Ohm, 20W a 4Ohm).la bobina è di buona qualità e il filo ha un buon diametro (supporta bene potenze fino a 50W RMS) i condensatori non sono top di gamma, ma lavorano bene.Consiglio di non esagerare con il volume per le prime 100 ore di ascolto, ho notato un suono decisamente meno elettrico quando si è "smollato" (dopo circa un mese di ascolto di musica di tutti i generi a volume medio e medio alto per 2h/gg) e anche un taglio di frequenza più amalgamato.comodi i connettori a baionetta che si accoppiano molto bene ai faston standard e che non richiedono saldature.Componente decisamente voluminoso e dal peso discreto, non è adatto a essere inserito all' interno di mobiletti di volumen inferiore a 4L
